[Octave-bug-tracker] [bug #61690] Behavior of sum() with empty inputs

[Sarrah Bastawala]

Follow-up Comment #1, bug #61690 (project octave):

Hello, I am working on resolving this bug and would like it to be assigned to
me. I saw that while 

sum([],1)

 behaves differently on Octave and Matlab,


sum([],2)

 gives, 

ans =

  0×1 empty double column vector

on Matlab, and


ans = [](0x1)

on Octave, which are similar enough. And by playing with how we set default
dimensions when we encounter an empty matrix in
liboctave/operators/mx-inlines.cc, I believe the bug can be resolved to give a
similar output for dim = 1 as well.
